Malignant melanoma metastatic to the tonsil

Metastasis to the oral cavity from melanoma arising in distant sites is very rare. The authors present three cases of melanoma metastatic to the palatine tonsil: two were cutaneous melanomas and one arose from the mucous membrane of the hard palate. Fewer than 30 cases of metastatic melanoma to the palatine tonsil have been reported, and none have been from mucosal melanoma originating from another mucosal primary site in the head and neck. From this perspective, one of the cases in this article is unique.The authors presentclinical histories of the three cases of melanomametastatic to the palatine tonsil. Two patients were still alive a substantial time after treatment. The case presentations indicate that careful examination of the head and neck should be part ofthe routine follow-up examination in all melanomapatients.
